Employers trucks were equipped with coil spring brakes that
automatically set when the trailer is disconnected from the tractor. Employer chocked one
wheel to hold the trailer against the dock as fork-lifts loaded or unloaded the trailer.
The Division cited a general violation of section 3664(a)(22) [securely blocked or
restrained and the brakes set]. Held: no violation. Decided in Yellow Freight 94-2565 that
functioning spring brakes securely restrain trailer.
